Sir, watching your vidoes on Marrow… I am confused about one concept.
{Topic: ANS}
In Nn receptor blockers, you say BP is reduced because of reduced N.E. secretion postsynaptically.
But sir, in parasympathetic system post-ganglionic fibres release only ACh. (Are there any exceptions? Or have I misunderstood the entire concept 
)
Please help sir
p.s. Your lectures have changed my perspective towards Pharmacology
Dear, block of Nn receptors in ganglions of symathetic nervous system (not parasympathetic) decreases release of NE in post ganglionic segment. This decreases BP.
sir what is the answer for this question you uploaded the day before yesterday?
